What is the project, and why should you care? At BetSymphony, we are embarking on an ambitious project to revolutionize the online gambling industry. Our vision is to develop a cutting-edge gambling platform that will serve as the backbone for multiple different brands, each with its unique identity and target audience. This platform will leverage the latest technologies to ensure a seamless, secure, and engaging experience for users across the globe.
As a Fullstack Developer on our team, you will own end-to-end delivery of the BetSymphony Backoffice and frontend applications — a mission-critical internal tool used by operators to manage players, trading, promotions, casino, payments, and reporting in a regulated environment where correctness, performance, and reliability are non-negotiable.
We are a team that embraces AI-assisted development as a standard part of the engineering workflow. We expect our engineers to actively use AI tools to accelerate delivery, improve code quality, and reduce time spent on repetitive work — not as an experiment, but as an everyday practice. You will be an excellent fit for this position if you have: Mandatory: * 5+ years of total software development experience * 3+ years of production experience with React, including complex state management (Redux / Redux Toolkit) * 2+ years of Node.js experience, with hands-on use of Express.js in a production BFF or API layer * Strong proficiency in TypeScript across both frontend and backend * Experience with unit and integration testing (Vitest, Jest, or similar) * Experience working in a microservices architecture, including an understanding of BFF layer integration * Familiarity with Docker and basic Kubernetes workflows * Proven experience using AI-assisted development tools (e.g., Claude, Cursor, GitHub Copilot, ChatGPT) in daily work (code generation, refactoring, debugging, testing, documentation) — this is a standard expectation, not optional * Strong English communication skills (B2+) * Self-organized, proactive, and comfortable working in a distributed team
Desirable: * Experience with JIRA and Confluence. * Experience with ElasticSearch * Experience in gambling or online gaming. * Experience with TDD development processes. * Strong interest in applying AI-powered tools (e.g., Claude, ChatGPT, Copilot, Cursor, or similar) to speed up day-to-day development tasks. * Proven ability or strong motivation to use AI to reduce development time, improve code quality, and automate repetitive engineering work.
Here are some of the things you’ll be working on: * New features development within the existing product. * Resolving technical problems as they arise. * Bug fixing of developed features. * Actively leverage AI-assisted tools to improve efficiency across coding, testing, debugging, and other SDLC activities * Writing Unit tests and integration tests. * Communicating with team members and the Product team. * Scrum ceremonies participation. * Mentoring middle- and junior-level colleagues may be required.
